Overview
XLSX to CSV extracts rows from a workbook worksheet through the shared browser-local worker path. This preview reuses the XLSX parser, row and cell limits, text download support, and spreadsheet formula neutralization already added for the P0 data tools.
Use Cases
- Convert an Excel worksheet into CSV for import or review.
- Extract spreadsheet rows into a plain text format without uploading the workbook.
- Create formula-safe CSV output from workbook cells before using downstream data tools.
Limitations
- This preview accepts one XLSX workbook and converts one worksheet at a time.
- Rows, columns, worksheets, input bytes, and cell sizes are capped before CSV output is prepared.
- Very large or complex workbooks can still be constrained by browser memory and XLSX parsing limits.
